Dynamic Friction 4804-27017 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-27017 is a GeoSpec fully coated plain disc brake rotor engineered as a direct OE replacement. Designed for passenger cars and light trucks, this rotor delivers reliable stopping power straight out of the box with no pre-installation cleaning or prep required.

GeoSpec Coating Technology:

• Full-coverage rust protection — All GeoSpec rotors are completely coated inside and out using a high-quality rust prevention coating, forming a durable silver-gray finish
• Superior corrosion resistance — Specially coated with a patented paint to form a durable and attractive silver-gray finish that fights rust far better than other conventional paint or zinc coatings
• Ready to install — The GeoSpec coating is processed dry, shipped dry, and ready to install without any additional preparation
• Safe bed-in process — The GeoSpec finish is simply and safely swept away by the friction material with no harmful effects

Premium Manufacturing:

• G3000 iron casting — Engineered and manufactured with premium G3000 castings duplicating precise original equipment vane configurations and fitment
• CNC-machined to tight tolerances — Each rotor casting is sent to state-of-the-art machining facilities where it is processed to the tightest tolerances available, then prepared with a non-directional finish to promote a faster and more even brake pad bed-in, along with quieter and smoother stops
• 100% balance-inspected — All vented rotors are 100% inspected for balance and are corrected if necessary with a state-of-the-art electronic mill-balance process

The DFC 4804-27017 is a plain (smooth-face) rotor ideal for everyday street driving and OE-style replacement. Its GeoSpec coating eliminates the need to degrease or wipe down the rotor before installation, saving time and ensuring a clean, contamination-free brake surface for proper pad break-in.
